To all whom it may concern.'

Be it known that I, JOHN T. S'rom, a citizen of the United States, and a resident ot Lakewood, county of Cuyahoga, and State of Ohio, have invented a new and useful Cleaning Apparatus, of which the following is a s ification.

My invention relates to apparatus adaptcd to clean objects or remove adherent matter therefrom by producing vibrations therein.

The main object of my invention is an efiicient and simple apparatus for removing adherent matter from objects in an etiicient and inexpensive manner with the le'ast expenditure of time and labor. Other objects will appear during the description of the apparatus shown in the accompanying drawings.

Many objects, such as boxes, foundry fiasks, castings, etc., have sand or other matter adhering to the walls or other parts thereof which matter must be removed. The removal of such matter has heretofore been done mostly by manual labor with a consequent expenditure of considerable time and expense.

The present invention aims to accomplish this removal of such adherent matter by means other than manual labor and thereby save considerable time and expense.

The present invention, although adapted for a wide range of applications, is illustra-ted, in the accompanying drawings, as one machine for carrying out my invention and as applied to an apparatus adapted to shake out the core or other sand from castings. It being understood, however, that an apparatus, embodying the features of the present invention, may be devised, with suitable modifications, to clean objects other than the casting shown or to remove adherent matter other than the sand'specified, or

to employ vibrator means other than that shown. v

In the accompanying drawin s, Fig. 1 is a plan View ofu an apparatus em odying the features of my invention and designed to shake out a casting; Fig. 2 is a side view of Fig. 1; Fig. 3 is a longitudinal section on a plane indicated by the line 3--3 in- Fig. 1

Y showing the several elements vmore clearly;

Fig. 4 is a cross section on a plane indicated by the line 4 4 in Fig. 2 showing the slide more clearly; Fig. 5 is a cross section on a plane indicated by the line 5-5 in Fig. 2 showing the slide and the vibrator more clearly; Fig. 6 is a cross section on a plane indicated by the line 6-6 in Fig. 2 showing the bed construction under the castin more clearly; and Fig. 7 is an end view oft apparatus as viewed at 7 in Fig. 2. Similar referencecharacters refer to similar arts -throughout the views.

T e apparatus shown in the drawings consists, principally, of the bed A the abut ment B, the movable member cylinder D.

The bed A may be made of an convenient form and height and is provi ed with the bars 10 upon which the casting E rests. The upper end 11 of the opening 12 in the bed A, under the bars 10, is formed as a funnel so thatsand, or core wires, or other material which is shaken from the'casting, may readily fall through the opening 12 and be disposed of from the bottom of the bed as by a pit, or conveyor, or other means. The liars 10 are provided as a rest for the casting E and to provide rigidity for the bed where the casting is o rated upon without encunibering the opening 12 with more material than is necessary so that the shaken out material may drop through this opening 12 without undue resistance or obstruction and thereby prevent clogging of this opening.

The abutment B shown comprises the bracket 13 secured to the bed A and two abutment stools Fand the s ring 14 for each stool. The bracket 13 has t e wall 15 which is provided with the conical openinoV 16. lach of the stools F is composed-of the head 17 and the stem 18 which latter fits loosely in and is ided inthe small end of d, and the this opening 16; ue to this conical opening,

the outer end of the stem 18 can move radially in all directions and thereby permit the head 17 to ad'ust itself automaticall to uneven or bevele surfaces often foun on objects to be cleaned. The springs 14 are f interposed between the wall 15 and the slide construction and one end thereof has iio made inte l with the slide 21 with good results. T e construction thereof, as a se alohate unit, permits of replacing this mec anism when worn without replacing the entire member.

The vibrator mechanism G shown consists of the housing 26 secured to the slide 20 as previously set forth and is provided with the walls 27 and 28 suitably strengthened by the ribs 29 and 30.

The vibrator shown, in the present instance a fluid ressure actuated vibrator, is composed of ,t e case 31' mounted between the walls 27 and 28 and held firmly therebetween by the bolts 32; the ears 33 are provided on the case 31 to hold the same in position sidewise and also down upon its seats 34 on the housing 26. The plunger 35 iits operatively into the housing 26 and operates between the percussion plates 36 which are countersunk'into the ends of the case 31 and abut-on the walls 27 and 28. The vibrator shown is indicative as to how a vibrator may be ap lied. Any sort of vibrator may be emp oyed and mounted in such a manner that the vibrations produced therewith are eiectivel transmitted to the housing and 'subsequent y to the casting. A fluid pressure vibrator, ver well adapted to the cleaning apparatus own, is shown and lclaimed in m pending gggplication for vibrators, filed arch 27, 1 Serial No. 628,158. No claim is made for any partlcular vibrator in the present application.

The c linder D is mountedon the wall 37 of the racket 38 which is secured .to the bed A. The iston 39 operates in the bore 40 of the c 1in er D as is usual in such structures. ne end of the piston rod 41 is secured' tol the piston 39 and extends through the stufling box y42 and out of the c linder where the other end thereof has the ss 43 which is provided with an opening for the pin 44.

A somewhat flexible connection is established between the piston rod 39 and the lug 23by the links 45 which are located on the sides .of the lug 23 and the boss 43; the elements of thisA structure are held together by the pins 24 and 44 as shown.

The jaw 46 is, in the present instance, secured to the housing 26 and is provided with the bevel facey 47 adapted to enga e the flange 48 of the casting E as seen in 1g. 2

This jaw ma be made integral with the housing 26 alt ough it is preferred that it be made separate as shown to the end that different jaws, adapted to dierent castings or other objects, may be substituted with very little inconvenience and expense.

It may also be noted here that the stools F can readily be substituted by other stools adapted to obects other than the castin shown although' the particular mounting o these stools shown in the drawin provides an abutment for man objects without substitution of other stoo s.

The plate 49 -is secured to the end of the slide-base 21 and the spring 50 is secured thereto for the urpose appearing presently.

The cylinder and the vibrator are, in the present instance, actuated by fluid pressure su plied to the three way valve 51, by the tu 52; the tube 53 leads to and supplies the vibrator with fluid ressure while the tube 54 leads to and su ies the cylinder D witn fluid pressure. he exhaust and valve mechanisms of the vibrator and the cylinder are not shown in the drawings since they may be of an suitable and well known construction an the details thereof are not claimed in this application. l

The present apparatus shown and described is distinguished from my ap lication for Method and apparatus for sha ing out foundr llasks and the like, filed Sept. 12, 1921, rial No. 500,193, and my Patent No.

1,447,694, March 6, 1923, for vibrator hookl wherein the objects to be cleaned are suspended from an overhead mechanism whereas,in the present invention, the ob'ects are supported from below by a bed an are held thereon more rigidly than on the hook. Generali it may be noted that an object of a more so id or ribbed construction is best cleaned by holding it to the apparatus more rigidly as in the present invention .whereas an object of a more flimsy construction is best c eaned by holding` it to the apparatus either semi-rigidly or merely suspendin the same as shown in the application an patent referred to.

The operationof the apparatus shown `and described is as follows v Starting with the elements in the positions shown in Fig. `3 and supposing that the casting E has been shaken out and is ready for removal from the apparatus.

First manipulate the valve 51 to admit fluid pressure to the ri ht hand end of the bore 40 in the cylinder whereb the piston 39 is moved toward the left. is move`- ment of the piston also moves the movable member C in the same direction and moves the jaw 46 away from the flange 48 of the the casting.

hand end of the movable member C abuts the .free end of the spring 50 and prevents A the piston from vlolently strikmg the wal137.

' bars 10.

The 'casting E is now released'and 'can be removed. from the ap aratus and 'another casting to be cleanedA 1s now placed 'on the The valve v51 is now manipulated to admit fluid ressure to the left hand end of the borev 1n the cylinder, thereby movingfthe piston 39, and consequently the movable r'nember C and the jaw 46, toward the right until the jaw 46 engages the flange 48v and pushes the casting against the .stools F and against the action of the springs 14 substantially to the position shown in Figs. 1, 2, and 3. The sprmv 14 cushion the impact of the casting on t 1e stools and the method of mounting the stools in the wall 15 rmits the heads 17 to automaticall adJust themselves to the beveled surface s own on the casting:l

When t e casting abuts the stools, the jaw 46 due to the bevel face 47 thereon,

holds the casting down on the' bars 10. as well as against the stools F. The amount of rigidity with-which the casting is held depends u on the size of the cylinder bore and the uid pressure. The valve 51 is arranged to retain the pressure in the left hand end of the bore vand against the left hand face of the piston and thereby retain the movable member against the casting' to hold the same-rigidly upon the bars 10 and between the movable member and the stools.

The valve 51 is now manipulated to admit fluid pressure to the vibrator as is well known in the vibrator art, thereby causing the plunger 35 to operate between an strike against the percussion plates 36 alternately.I Y

This striking of the plun er against the percussion plates produces vi rations in the housin 26 `which vibrations are transmitted to the lied as well as to the bars 10 and to the jaw 46 and, in a measure, to the abutment B through the bed and the bars. From these elements, the vibrations are transmitted to the casting wherein the produce certain molecular action whic oosens and shakes ofi' the sand or other material from the walls of the castingwhich sand or other material can readil fall down through the opening 12 from wliere it can readily be disposed of.

After the casting is shaken out, thc valve 5l is manipulated to stop the vibrator and to release the fluid ressure from the left hand end of the cy inder bore and admit fluid ressure to the right hand end of the cylin er bore which again is the beginning of another operation as set forth.

As general remarks, applying to the ar ticular apparatus shown and describe as well as to ap aratus of other forms, I have found-that tliie abutments with the springs shown give better results than a solid abutment, not onlyin effective shaking out or cleaning but. also in preventing breakage of objects. The automatically 'adjustable stools roduee better vibrations in the objects since theyl'always bear firmly against the same whic .usually have uneven surfaces.A The use of two abutment stools and one jaw acting substantially midway between them produces a better vibratory effeet in the object than when they are directly opposite of each other. Any sort of vibrator may be em loyed as long as vibrations are produce and transmitted to the object. Any sort of holding means may be employed as long as the object is held rigidly in such a osition that vibrations are produced therein b a vibrator mechanism.

'Modiications, otlier than those pointed out, may be made; therefore, without limiting myself to the precise construction shown and described and pointed out.
